Abstract

A method of making an electrolytic cell in which an electrolyte layer (12) of an intermediate sintered form (1) is coated with a pre-coat layer (22) containing electrically non-conductive particles (24) of less than about one-tenth of a micron in size to fill in defects (14, 16, 18, 20) existing within the electrolyte layer (12). The pre-coat layer is removed so that the electrically non-conductive particles (24) remain within the defects (14, 16, 18, 20) of the electrolyte layer (12). The cathode layer (26) is then applied to the electrolyte layer (12) with the electrically non-conductive particles (24) in place within the defects (14, 16, 18, 20). The intermediate sintered form (1) is fired with the applied cathode layer (26) to produce the electrolytic cell.
